Can you change the changelog note to match our expected format? https://googlecloudplatform.github.io/magic-modules/contribute/release-notes/

[slevenick]

Need changelog note update, otherwise looks good. Tests ran in CI

[xuchenma]

Thanks for the review; updated the release note to remove the trailing line.

[slevenick]

I'll update it for now, but in the future please use the standard format
